Authorities in southern Switzerland say a woman and her 3-year-old daughter were killed when a landslide swept over their house.

Zurich daily 20 Minuten reported on its website that crews found the body of the 31-year-old woman and her child buried in the rubble of their home in a remote area near Lugano early Thursday.

Police, firefighters and other rescue crews using search dogs had searched overnight in the hope of finding the two alive after the landslide Wednesday evening.
